A motor iO is herein illustraed proviiied wieh fou cylinders 11 arranged en bloc and having an intui'e nmniiold 12 leading from the curhureier 1.0 to the ugper portions of the said cylinders communicating (iireeely Wiifih Io ether by means of cross head poriior ii 1 Que ranches 15 of the :mzihi'iold i ight iii of which is aiii'ucheci "so er aiter the usual manner of bin air intake valve for the n'mnii'olrl upright 16 is arranged in the form of a cylindrical (Zfi iilg 17 connected by means of a stub pipe uiih the said upright m; a point helnveen Elie c: rhureier and the top or ihe up right, 1i? where the branches 15 spread ou" wariily from {he upright. The partition 19 is arranged w 1m the casing 17 at a point; above the er ruiice opening thereof arranged for the stub pipe 18 and provided with an eiiuler valve seat 21 upon iis upper 17 through the ppeuhot'hom thereof and ar-' ranged with an annular notch or groove for I seating upon an annular shoulder 26 kite-- riorly of the casing 17, While the bottom 23 is retained in seating engagement with a similar shoulder 27 2% the lower end of the casing 17 and whereby the pi eon casing 22 is eeeurei axially oi fshe valve casing 17 aucl reviijieii with air inlet ports; 8 through row eiwpeiues between ho'tiom 23 and partition 19 and adjacent the said partition being arranged about the air outlet 20 of the saidvalve casing.

The valve casing 17'is provided with a top 29 having a central opening 30 for the entrance of air of substantially the same diameter as the piston casing 22 and provided with an inwardly arranged alve seat 31 positioned opposite to and parallel with the aforementioned valve seat 21. A valve 32 of the form best illustrated in Fig. 7 of the drawing is shiftably arranged within the aising 17 having a stem 33 provided with a piston 34 at its inner end arranged for lon gitudinal movement within the piston casing 22 and having an air tight packing carried by the said piston for making a tight engagement with the said piston casing. A valve disk 36 is carried by the outer end of the stem 33 between the valve seats 2i and 31 being of greater diameter than the piston 34 and casing and of substantially the same diameter as the said oppositely arranged valve seats which the disk 36 is adapted to engage during the operation of the device.

A con'nnunicating pipe 37 is connected by means of a union 38 with the cap perforation 25 and by means of a nipple 39 with one of the manifold cross heads 14 at a point adjacent an intake valve (not shown of one of the motor cylimlers 11. A helical spring 40 is arranged within the casing 22 being tensioned between the cap 24 and the adjacent end of the valve piston 34 whereby the valve disk 3' is normally maintaiin-d in seated engagemcnt with the upper seat 31' if the valve casing 17.

'hen the motor is at rest. the valve will be arranged closed as above noted inthe position illustrated in Fig. 2 of the drawin'g. As the motor 10 is started in operation a vacuum is created within the piston chamber 22 bcn atlr the piston. thereby lowering the piston and seating the valve ill; upon the partition seat 21 thus cutting off the admission of air. As the. speed of the motor increases; the vacuum within the pipe 37 and beneath the piston '34 will be decreased allowing the spring 40 to slightly unseat the valve. as illustrated in Fig. 4 of the drawing and whereby the air will pass through the opening 30 around the valve disk. so and into the casing 22. out through the ports 28 in the annular chamber -tl of the casing 17 between the said casing partition and bottom and thence through the stub pipe 18 into the manifold upright 16. The usual running position of the valve 32 for admitting the maximum amount of air to the manifold upright 16 is with the disk 3i) positioned substantially centrally between the valve seats 21 and 31, while a decrease in the speed of the motor increases the vacuum within the vacuum chamber 42 of the piston um in the chamber 41 is greater than running at high speed, this being for the rea son that the butterfly valve (not shown) of the carbureter 13 is in a closed or partially closed position during the slow speed of the motor and by allowing little or no entrance of air, the suction of each piston of the motor is at its maximum and creates'amaximum vacuum within the'chamber 42. As the butterfly valve is opened to increase the speed of the motor it opens up a free entrance to the atmosphere decreasing the suc tion within the intake 12 and thus decreasing the vacumn within the valve chamber 42. The spring 40 is arranged of the proper tension to maintain the valve closed upon its upper seat 31 when the motor is idle and also when the vacuum within the chamber 42 is reduced below a predetermined degree.

There is no communication between the chamber 42 and the air passages above the 7 piston 34 and it will thus be seen that a simplc device isarranged whereby the air inlet to the manifold upright is automatically controlled by an intake valve of the motor in a manner to insure the greatest etticiency of the motor by proper regulation or dilutionof the explosive mixture after leaving the carburetcr.

\Yhile the form of the invention herein shown and described is what is believed to be the preferable embodiment thereof, it is nevertheless to be understood that minor changes may be made in the form, proportion and details of construction without de parting from the spirit and scope of the invention as hereinafter claimed.
